Central park is a rectangle with an area of 840 acres. it is 1/2 a mile wide. one acre is 43,560 square feet. two people start at the southwest corner at 1: 30 pm and start walking round the park in opposite directions. one walks at 9 mph, the other walks at 4 mph. how long until they meet again?

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
